3D Avo Processing: A Case Study From The Gulf Of Mexico

3D AVO is one of the emerging seismic technologies that is now being used more and more, as a tool for hydrocarbon exploration and field development. A key component of this technology is the 3D pre-stack processing for AVO. The improvements made in the past few years in preserving the seismic amplitudes in the 3D pre-stack processing sequence give more confidence in the resultant AVO analysis. The purpose of this paper is to illustrate the effects of a carefully executed 3D AVO processing on a data set acquired by Schlumberger Geco–Prakla over a High Island prospect in the Gulf of Mexico. The results of this 3D AVO processing and analyses were confirmed by the drilling of a successful discovery well.
